FPGA-based Digital Video Resolution and Playback
Xu Lin · Telecommunication Engineering · 2005
An FPGA-based implementation of digital video resolution and playback for net meeting knot-device is proposed.Before video compression, chrominance signals U,V and luminance signal Y should be separated from each other in every frame.Through communication between DSP EMIF and FPGA,this design implements video data's capture and playback based on a single FPGA chip.This paper gives out the frame resolution method and the implementation of DSP EMIF controller and SDRAM controller.The engineering application shows that this design simplifies the complexity of DSP algorithm and improves the real-time characteristic.
